[Request] Indication of user gender by avatar


Users are required to enter their gender during registration (by means of custom field in user profile). Rather than showing a small icon or text below the user information block, is it possible to show their gender directly with a small addition in their avatars?

Such as avatars showing below: red for male, green for female, for example.


A thin outline is added around the avatar image which shows different colors depending on different genders.

1) Thickness, color or even opacity of the line should be configurable.
2) It's better not a destructive modification to the avatar image
3) It also applies to the default avatar if the user didn't upload a custom avatar.
4) Note that the avatar could be configured to be round, square or rounded corner square so it should apply to all shapes dynamically.
